For people from the grassland, both men and women, love to drink, so this cup of draft beer is not much different from boiled water for Wang Xiaoyu.

Drinking and chatting at the same time, this way of interacting with old friends also makes people feel relaxed, but at this time, Wang Xiaoyu's heart is still a little strange, Brother Zhenhua came to Mia, is it really for old friends to catch up?

It's not in line with his style.

"Qin, I really didn't expect us to meet again so soon." Mia drank a few sips of beer, her face flushed, and she spoke more boldly: "Since I returned to Germany, I have always missed you..."

"Ahem, ahem." Qin Zhenhua coughed twice, he knew that foreigners were very bold, and if they thought in their hearts, they would say it with their mouths, but this was just thinking, they would not behave out of line.

"Mia, I came to you for some small things, and I want to ask you for help." Qin Zhenhua said: "After all, I only have one friend here, and I can only look for you." ”

A smile appeared on Mia's face: "I know that your motives are not pure, if it weren't for my help, you wouldn't want to come to see me at all, say, what's the matter?" ”

"My wife is doing academic research with her supervisor." Qin Zhenhua said: "In their university laboratory, they want to import a four-axis single-sided fine grinding machine for optical use. ”

As soon as these words came out, Wang Xiaoyu's heart was filled with gratitude and guilt, how could she doubt her husband? Although they are not officially married, the two are already engaged, even if they are two people, he wants to meet his confidante, and he will take him with him, and he will not secretly go out for a tryst, and, most importantly, for work.

Every time you go abroad, there will be a corresponding university quota, and the Capital Institute of Technology is in industry, so naturally there are opportunities, and by the way, you can also complete some academic exchanges.

Take it now, Qin Zhenhua said that the four-axis single-sided fine grinding machine used in optics is indeed a piece of equipment that they urgently need, and when doing scientific research, without this equipment, it will take a lot of time to grind manually, and the accuracy cannot be guaranteed.

On the way here, everyone sat together and chatted, Wang Xiaoyu remembered that Professor Cao also mentioned this thing, but unexpectedly, Brother Zhenhua remembered it, and actually came to discuss it with Mia in person?

Hearing Qin Zhenhua's words, Mia stared at Qin Zhenhua for a long time with a smile on her face, and then said, "In the university laboratory? You should have a large demand for spherical grinding machines, right? Planar, or four-axis, high-precision, I guess, you guys are going to grind the prism? ”

Mia is also quite smart, and she guessed Qin Zhenhua's intentions at once, he came here to find a way out of civilian heavy trucks, but since he came over, he always had to do a few more things to save money on air tickets.

This kind of optical processing equipment, and then linked to Qin Zhenhua's identity, Mia immediately guessed Qin Zhenhua's thoughts.

This is to prepare for a new generation of fire control systems!

The earliest fire control system was an optical lens with a complex scale on it, and then, depending on the situation of the target, various firing parameters, wind direction, etc., were stapled, and then aimed and fired.

This fire control system is simple and primitive, and can only be stopped after stable shooting, which is certainly not able to meet the needs, and later, the turret of the tank gun began to use a stabilization system, through a certain amount of advance, with the ability to shoot automatically, and even added an automatic loading system, a lot of data is automatically bound.

However, in the era of rapid development of fire control systems, this automatic metering system has long been outdated. When the introduction of the L7 tank gun from the United Kingdom, it also corresponds to the introduction of the relevant disturbance fire control system, which can measure more error parameters of the tank gun compared with the automatic meter fire control system, such as gun inclination, movement state, etc., and to eliminate, and from the United Kingdom to introduce the improved disturbance tank fire control system, it adopts the electrical synchronization method to realize the automatic synchronization of the gun and the line of sight, thereby improving the response speed and accuracy of the fire control system.

However, this is still the simplest fire control system, and its simplicity lies in the fact that the fire control system is subordinate to the artillery, and where the turret turns, the fire control system turns, and then searches and aims at the target.

In actual combat, this is not a good way, a better solution is that the fire control system first searches for the target, and then the gun points to the target, and the fire control system directs the artillery, which is the command ritual fire control system.

The aiming line of this fire control system is stabilized independently by gyroscope, and the gun commander does not move from the aiming line to look out at the target and the background, so it is also called a stable image fire control system.

Now, to develop a new type of tank in China, the fire control system is also a difficult hurdle to overcome, for a machine factory, just to the following supporting manufacturers to put forward requirements, but this efficiency is very low, now, in the development of their own tanks, the fire control system, Qin Zhenhua also paid attention to the problem, and the research and development of the fire control system, the team led by Professor Cao, is one of the backbone.

Of course, I have to help in any way I can.

For example, the scope follow-up system of the Leopard 2 main battle tank is stable in the upper mirror, the stable field of view is large, and the optical performance is better, but the requirements for the device are higher, and the first thing to overcome is to stabilize the lower mirror scheme, using the gyroscopic direct stabilization of the 120-degree prism in the sight, the structure is relatively simple, and the cost and cost are relatively low, and among them, the 120-degree prism is directly related to the quality of the entire fire control system.

Of course, the downward trans fire control system, is only to solve the problem of whether there is or not, this fire control system is simple in structure, but also has its disadvantages: when the artillery movement speed is faster or the angle is larger, the error increases rapidly, this shortcoming, in the fierce battle, will drag down the operation of the gun commander, as for another important reason, is that it is impossible to connect the night vision system image, that is, when fighting at night, the gun commander can only return to the past stable line to work, that is, to stabilize the line of sight instead of the image, The practicality is greatly reduced.

There are two main schools of domestic optical equipment, before the war, it was imported from Germany, after the war, it was mainly imported from the Soviet Union, and those equipment in the Soviet Union, after these years of use, the accuracy has begun to deteriorate, and it can not meet the needs.

After all, with optical equipment, Germany is still the first.

"Well, prisms, flat mirrors, anything can be grinded." Qin Zhenhua said.

"So, what's the use of you looking for me? Find the manufacturer directly, the first-class manufacturers are Raul Company, Lycra Company, and their equipment there is ready-made. Mia continued.
